HAHA! I love those questions! One, in particular, was hilarious but I didn’t click on it. Just my luck someone would come along and check out my browser history and start to wonder why I’m looking that question up! lmao 😉 But, I’m thinking I’m about to break down and check out what kind of funny answer is there. And who knows, I could start a very lucrative business in my crazy neighborhood!
Hello Printer Chat friends. As we promised, we bring you the questions we collected from our own research about this subject. We also bring our own answers to them. We hope you enjoy them. We will publish our post in Spanish with our questions and yours in Spanish language very soon in our webpage, stay tuned!!
+And what is 3D printing useful for?
-Teaching, engineering, medicine, toys, DIY, cooking, fashion, writing great posts in my blog…
+Did you print something useful of only junk?
-I did. I printed a thread for a drum, a piece for a broken lamp, a support for a go-pro, some boxes, an ashtray,
+Can you print pancakes? I saw in “El Hormiguero”….
-The printer in the video is the same as I have with an adapter, so if I bought or built the adapter, I could print pancakes
+Can you print dishes, glasses or cups?
-I can, but is a bit difficult to made a waterproof container with PLA, first time I printed a glass, the water poured from every single wall.
+Is it bad for my health?
-If you print certain materials in a closed room it could be. You need to have a properly ventilated place for 3D printing. And it for sure will be bad for your finger´s health to touch the nozzle when its hot.
+Can it have a smoother finish?
-It depends of the printer you use, the material, the technology (FDM, SLA…) mainly. You also cam use some methods for improving the finish after printing, like sanding or using acetone juice.
+Can you post-process it?
-Yes you can sand or paint it after printing. But it also depends on the material
+Is the material expensive?
-Not much, I consider it cheap. Near 20€/ 1kg
+Which are your printing settings?
-It depends on the print, I use to make 5% infill models, but I change the height of the layer depending on the model. I also use to put a 5cm brim in all my prints.
Hi again, we forgot some questions
+How many time does this take? Can you mentally calculate how many time will this print take?
-NO, i can invent how many time will it take, but better wait until I ask to Repetier Host
+Aren´t fragile the 3D printed pieces?
-It depends on the internal structure, but you can do very solid pieces with the right settings.
+Which size can you print? Which is your best resolution?
-Our print area is 215x210x180, our best resolution is 0.2mm
Glass bed should not crack if made of the right kind of glass. For 3d printing you need tempered borosilicate glass which will withstand high heat and multi temperature changes.
It is easily obtained online fairly cheaply. See here https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=Tempered+Borosilicate+Glass
You will want to buy the correct size as it is not easy to cut.
I use Sculptris, http://pixologic.com/sculptris/
Autodesk Fusion 360, https://www.autodesk.com/products/fusion-360/overview, free for hobbyist
Meshmixer, http://www.meshmixer.com/, also free
Lithopanes, forget where i got but a free download, though you have to change the menu from portugese to English to use
Cura 3d for slicing, https://ultimaker.com/en/resources/manuals/software
a few others that came with the printers, like Pango and Repetier
“What do I need to know about 3D printing before starting or buying a 3D printer?”
You know people ask that question a lot how ever I personally find that 3d printing is a learn as you go (or rather run in to issues) type of thing. My personal answer is for a first 3d printer (buying wise) is don’t go too cheap how ever don’t go to expensive either (assuming personal printer not company). If your looking at printers for a company go with something that has a good reputation with strong company / user support. If your looking for yourself look for something with at least a strong user community behind it.
Personal (non company): I’d go with something like a Wanhao (low price), CR-10(low price), Prusa(mid range)
Professional: I’d spend out the money for something like the Ultimaker(high end)
Why I’ve chosen this is simple you don’t know how well the bug will hit you so if you don’t like it your not in too deep out of pocket with the cheaper printers (but don’t go too cheap). If you like it you can always sell your original printer and upgrade to the Ultimaker or other higher end products. Nothing in 3d printing is perfect no matter what you will have to stop scratch your head then figure it out (even with high end printers).
At work we have a $6000 3d printer that prints no better then my Wanhao that costs $300 (well ok with the mods that make it better more like $400, in my case a thicker y-carriage and z-brace mod, I have other mods but those 2 I’d say are the best 2) so time, learning, tinkering you can make a fairly cheap printer go far.
Remember we all have our opinions and thoughts this post is mine from my own limited experience of usage. Take it with a grain of salt.
